Patent DE-4019161-A1 (DE)
Inventor: GONZE EUGENE VICTOR
IPC: F02B1/04
Filed: 1990-06-15
Abstract: A fuel control of an engine of a motor vehicle adapted for multi-fuel operation uses a fuel injection system in which fuel in a liquid mixture of first and second combustible fuels such as gasoline and methanol is injected in pulses of controlled duration at a predetermined pressure to achieve a predetermined air/fuel ratio. The first and second combustible fuels have different viscosities, so that the viscosity of the mixture changes with its composition as well as fuel temperature. The pulse duration is varied in response to detected fuel composition and fuel temperature so as to compensate for the variation in viscosity of the fuel mixture and thus deliver the required amount of fuel with each pulse. A variable pressure injection system is also described.

Title: Injection moulding hollow articles - by injecting nitrogen into interior of hot shot in mould, injecting cold gas through two other needles to accelerate cooling
Inventor: DANNEBERG HORST
IPC: B29C45/17
Filed: 1990-08-02
Abstract: Injection mouldings are produced with one or more internal hollow spaces in the plastic melt. In the process, when the moulding stage has been completed the internal spaces are purged with a cold medium in one operation. - The two-part mould has three holes in the top tool.

Title: Control system for airbag - has processor control to inflate at rate matching severity of crash
Inventor: MATSCHI HELMUT DIPL ING
IPC: B60R21/01
Filed: 1990-12-20
Abstract: Each airbag of the system (R) is linked to a pressurised control chamber (B) from which the gas is fed via a control valve (V).

Patent DE-4104951-A1 (DE)
Inventor: HUBERT ALEX PROF DR
IPC: G01R33/06
Filed: 1991-02-18
Abstract: The multi-layer system (2) with magneto-resistive properties disclosed has at least two thin ferromagnetic layers (3, 4) with, between them, a thin non-magnetic layer (5). The invention calls for the thickness (d) of this non-magnetic intermediate layer (5) to have a pre-determined value which is dependent on a discrete transition between ferromagnetic behaviour and anti-ferromagnetic behaviour of the multi-layer structure (2). The thickness (d) of the non-magnetic intermediate layer can be conveniently defined by observing the domain pattern as a function of the layer thickness (d), making use of the magneto-optic Kerr effect.
